YDL 4.0 and "Old World" Macs

[yellowdog-general@lists.terrasoftsolutions.com]

Hi,

I'm running YDL 3.0.1 on several "Old World" Macs (7600s with upgrade
cards, Beige G3). It runs great - it even recognized really cheap
generic USB ($4.99) and FireWire ($9.99) cards, USB scroll mice and
an iPod via plug and play.
Now I learned that YDL 4.0 will only "be supported" on "new world"
Macs. What does that mean? Will it really be impossible to install it
on older machines?

Regards,

Helge
